A) \[\frac{No\,\,of\,\,teeth\,\,on\,\,first\,\,drivers}{No\,\,of\,\,teeth\,\,on\,\,last\,\,follower}\]

B) \[\frac{No\,\,of\,\,teeth\,\,on\,\,last\,\,follower}{No\,\,of\,\,teeth\,\,on\,\,first\,\,drivers}\]

C) \[\frac{\text{Produc}t\,\,of\,\,teeth\,\,on\,\,the\,\,drivers}{\text{Product}\,\,of\,\,teeth\,\,on\,\,the\,\,follower}\]

D) \[\frac{\text{Produc}t\,\,of\,\,teeth\,\,on\,\,the\,\,follower}{\text{Product}\,\,of\,\,teeth\,\,on\,\,the\,\,drivers}\]
